SWITCH STAND.

Application led June 10,`

To r/,Zlwwlm it nuca/'concepiti y Be itlrnown that-'1, FRANKU.riNDnnsoN, acitizen of the United States, residing at Cincinnati in thecountv of Hamilton and State of Ohio, have invented certain.l new anduseful Improvements in Switch Stands,-

.of `which the 'following isaspecication;

Its object iste simplify theconstruction and operation o1' switch-standsotthis character, to effect economy intheir maintenance, and,u wheredesirable, as in yard usen to dispenselwith the use-of latches forholding the switch in closed position. Other objects, pe-f culiar to thepresent invention, as well as in.- common with those '01 the mentionedpatents, will appear inthe course of the ensuin g description;

lv` attain these objects by the device illustrated, for example, iny theaccompanying drawing, in which Figure 1 is a sectional'plan view oit'the switch-stand, the majorpart o'fithe section being on the plane of-theline 1-1 of 2 through .the upper part oit the casing, and a minormiddle part of the sectionl beingv on the plane of the line 1-1 of Fig.2 throughv the iront shaftV bearing;

Fig'. 7 is a similar view of -thehollow key-f pin for thefront-bearingbushingg and Fig. Sis apartial sectloncorresponding tosection 1n a` vertical transverse, plane.: through thelcentcr of thetarget shaft,v better4 showing the connection olf thev intermediate'craul. and direct-switch-throwing.eranlrcons nection, andA also showing'a inodiied switch'-I connecting` rodand pin therefor.

The base of the stand comprises the middle.- part 1 with feet 2 atopposite ends, extend ing down and being' provided with openings fthrough which they are spiked-or screwed e tolthe respective cross-tiesor head lblocks o'ls the switch, not shown. At itheopposite ends oitheflat middle part 1 are downwardlft7 openingv sockets 3 with openingstorpassage of bolts.

5 at the rear,l the latter 'having' the concentric bearing opening-6 inlliront-to-rear salinement with the tront'bearing. J ust tothe rearof'this front bearing?y 4 the base-has the depression 7; and at oppositeends ot the baseziniddlelat part' lare u pstandinn pedestals 8, eachwith an` upper transverse openy ingr and a lower transverse opening,receivingthe ends of A.euide-bars 9, which thus en# tendI across 'thebase, above the rear of'thiefl socket parts 3 of the nase when'thecasing,`

which has au open bottom, is placed down over the interior working partsassembled on the base, with the casing; lower edges fitting closely onthe base middle tlat=part l. along the edges or" thev latter. Thecasing' is held down on the base by bolts 13 through ears on the'baseand casing at opposite lsides ofthel :front-bearings 4 and 10, andboltsl in the base sockets 3 and up through thecasing ears 12.

The handle-lever 14 is adapted:todos thrown to one side or the other andto rest an one oil* the other olf the lever-rests 14C,

This base also comprisesthe-.front shattf-beaasng el. andthe segmental'extension f ice which it will be understood are spiked or otherwisesecured to the ties or head blocks of the switch, not shown. At the treeend ot this handle-lever 14 is the weight-handle 15 of approved design,and at the other end, preferably forged integral with the handlelever,is the crank-shaft 16, lyingl inthe front bearings 4l and 10 andextending bach over the depression 7.

The handle-lever crank 1i' comprises a hub 18 litting on the inner endof the shalt 16 and held thereon by a key-pin 17 and a transverse pin17, and also compl-'res wrist 19 extending rearwardly; and it isradiallyalined with the lever lfl.

The rack or slide member 2l) comprises the upper middle part 21 withupper side parts 22 extending rearwardly'trom its opposite ends,downward. projections or teeth 23 at the front, equally spaced troni therertical 'median line of the meinljier 2OU and rear bearing parts 211extending down 'from the upper side parts 22 and joined to theproy*Jeetions or teeth 23, and having transverse tween the downwardprojections o 'up through and holes 25 above'and below` which tit on therespective guide-bars 9- These guide-1min 9 are held against lengthwisemovement in their supporting pedestals S `by cottcrs 9 through the barsagainst the inner sides ot the pedestals 8; and the rack or slideinember 20 thus 'is adapted to slide along the ba 9 across theswitchstandnl as driven bythe crank 17 'having its wrist 19 eno ningbcteeth 2% of the member 20. lThe middle ot the upper middle part 21 otthis member 20 preferably is depressed, as'at 26; and alone; oppositeends oit the top ot the menibcr` trom 'Front to rear, are the upstandingjaws 2T, with narrow undepressed parts next to their inner sides atopposite ends oi the mic lli-depression 2th These undepressed par. andthe inner sides of the jaws 2'?. may be linished Vsmooth and straight,

yThe target-shaft 28 will be nnflerstood to be o'tsuitable design inits. upper par@ not shown, to support a target or lamp or other inea-nsat any required height: and the intermediate crank 291 ot radius .suitedto the throw oit the rack member 2O.y has tho hub 30 receiving thetarget-shalt down throughit. The bearing' block Pil is dat, withparallel Opposite sides and a central circular lop'eningv and titsslidingly between the i 27 of the member 2O anddowi'i on the undepressedadjacent parts ont the top et this member` The arm ot the intermediatecrank 29 has near its front end the downwardly projectingbearing lug illfitting snug the central opei'iing oi" this block ,Si ormthe depressedmiddle part 2G oi the top oli' the member 20. by which it has annaleclearance therefrom; while the target-shaft entends bears in the opening11 of the casinfr groove in the bottom of the hub 30, and thetarget-shatt 28 has its lower end screwed into thev center of this hub:1thus holding it lirinly to the intermediate crank 29. The crank 34 alsocomprises the opposite radial arms 36 integral with the hub and having'openings up and down through them near their outer ends. t

As shown in lligs. l., 2 and 3, the switchconnecting rod 37 simply lieson the top of one of the crank-aims '36, with a pin having a lowerreduced part fitting in the crank-- arm opening` and an upper largerpart einbraced by the rod 3T. At the A junction oit 'theseparts of thepin it is still more reduced by a groove 38 around itfso that the 'pin3S will breuk before any part of the switch or other part ot theswitch-stand breaks, in the event oiI the switch being run through inthe wrong direction. Tlnsgis desirable when the switch-stand is used inwirds, where such running through is 'trequent and the ten'lporaiyderange'ment oit the f installation' is more permissible than on mainlines, because of the lower speeds, ab- 'v sence o'f passenger tra'llio,and more `treuuent opportunity lor inspection ot the switches.

ln the modification shown in Fighe, the switch-connecting rod 237 hasa-tork, the members oit which lie` above and 'below the crank-arm 36,and the pin 38, passing down through the rod members and the arm 3d witha head bearing on top of the upper rod niernben is not reduced invcross-section as y for the handle lever 1/1, would replace the simplelever-rests 14 shown in Figs. 1, 2 and 8. ln yard use, however, withy mylpresent inventiom no latch is needed to hold the switch. closed,because the crank 17., at either end of its throw oil 1800, lieshorizontal, or

y on dead center with respect to the rack or slide 20; so that any forceat the switch .point-rails7 tending to open the switclnis positivelyresisted by this crank in this position, through the medium of the rack20, intermediate crank -Qyrigidly clutched directswitch-throwing crankSe with its integral 1 arnese throne-li in the 'wrong direction; 'theleverage n. n f y N 1 Q ljieingsuchl that Athe handle-weight lo nolds`the switch yclosed under normal ti'a'l'li'c without se'Av cured by pin38.

simplicity of the crank-and-rack `combinal -tion, in which the rackamounts to a twotooth rack yand the crank to a one-tooth pinion, neverunmeshed from the rack teeth evenl with extreme looseness of thecrank-shaft bearing, ymakes provision for maintaining vthis bearing evenless necessaryfthan with any of the numerous multiple-tooth gearingconnections, including my, priorl inventions referred to herein.
